Objective To elucidate the related risk factors for the cardiorenal syndrome(CRS),and to provide a reference for the prevention and treatment of CRS. Methods A retrospective study was conducted on 269 patients with chronic heart failure. The subjects were divided into two groups in accordance with estimated glomerular filtration rate(eGFR):patient group(CRS group),eGRF<60 mL/(min ! 1.73 m2)and control group,eGRF≥60 mL/(min!1.73 m2). The patients'general information as well as the related clinical lab indices and accessory examination indi-ces were collected. The risk factors for chronic heart failure and renal insufficiency were analyzed with multivariate logistic regression analysis. Re?sults The prevalence of chronic heart failure patients suffering from CRS was 26.39%. The single factor analysis showed that there were statistically significant differences between the two groups in terms of age,body weight,history of hypertension,and history of diabetes(all P<0.05). Compared to the control group,uric acid,cystatin C,serum urea nitrogen,brain natriuretic peptide,glycosylated hemoglobin,high-sensitivity C-reactive pro-tein,and left ventricular end-diastolic diameter in the CRS group were significantly higher;white blood cell count,hemoglobin,albumin,and left ventricular ejection fraction were significantly lower(all P<0.05). There was no statistically significant difference(P>0.05)between the two groups in regard to white blood cell count,glutamic-pyruvic transaminase,glutamic oxalacetic transaminase,cholesterol,triglycerides,high density lipoprotein,low density lipoprotein,troponin I,serum free triiodothyronine,serum free thyroxine,or thyroid stimulating hormone. Multivariate logis-tic regression analysis showed that older age,low body weight,history of hypertension,history of diabetes,hypoalbuminemia,superb sensitivity C-re-active protein levels,high uric acid,high cystatin C hyperlipidemia,and low ejection fraction were independently associated with the occurrence of CRS. Conclusion Older age,low body weight,history of hypertension,history of diabetes,hypoalbuminemia,high-sensitivity C-reactive protein levels,high uric acid,high cystatin C hyperlipidemia,and low ejection fraction are the high risk factors for CRS in heart failure patients and are inde-pendently associated with the occurrence of CRS. Early identification and control of these risk factors are important for the prevention and treatment of CRS.

Objective To investigate the expression of vascular endothelial growth factor (VEGF) in colon cancer and its relation with the microvessel density (MVD) and p53 gene. Methods The expression of VEGF, p53 gene and MVD of different region of colon cancer were studied by immunohistochemical method from 68 by surgical resected specimens. Results The positive rates of VEGF, p53 and MVD in colon cancer were significantly higher than those in peritumor and normal tissue. The expression of VEGF and p53 positively correlated with depth of invasion, lymph node metastasis, distant metastasis, vessel invasion and Dukes' stage, but their relation to the histologic types was not significant. The MVD in p53(+) ( 34.6 ?12.2 ) and VEGF(+) (31.2?12.6) tumors was significantly higher than that in p53(-) and VEGF(-) tumors (15.0?7.9; 12.7?6.3, respectively, P

OBJECTIVE To investigate the distribution and resistance of pathogenic becteria isolated from inpatients with lower respiratory tract infection in Department of Gerontal Respiratory Medicine during from Aug 2006 to Aug 2007.METHODS All the clinical isolates from sputum were analyzed retrospectively.RESULTS There were 211(79.8%) strains of Gram-negative bacilli,40(15.2%) strains of Gram-positive bacteria and 12(6%) strains of fungi.The most important Gram-negative pathogens were Klebsiella pneumoniae.Pseudomonas aeruginosa,Enterobacter cloacae and Escherichia coli.Strains of Gram-negative bacteria were susceptible to imipenem,cefoperzone/sulbactam and amikacin,strains of Gram-positive pathogens were susceptible to vancomycin,nitrofurantoin,cefazolin and imipenem.CONCLUSIONS Gram-negative bacilli are the major pathogens in lower respiratory tract infection in Department of Gerontal Respiratory Medicine and the dominant is conditional pathogen.Rational use of antibiotics is important for the containment of bacterial resistance.

Objective To evaluate the effects of different rates of remifentanil infusion on cardiovascular response to tracheal intubation in older patients. Methods Thirty ASA Ⅰ-Ⅲ patients aged 65-75 yrs weighing 50-80 kg scheduled for elective abdominal operation were randomly divided into 3 groups (n = 10 each) according to the remifentanil infusion rate: group A 0.05 ?g?kg-1?min-1; group B 0.1 ?g?kg-1?min-1 and group C 0.15 ?g ?kg-1?min-1. The patients were premedicated with intramuscular phenobarbital 0.1 g and atropine 0.5 mg. Radial artery and subclavian vein were cannulated for BP and CVP monitoring and blood sampling. ECG, BP, HR and SpO2 were monitored during anesthesia. After 10 min stabilization induction of anesthesia was commenced with remifentanil infusion for 10 min. Midazolam 0.1 mg?kg-1 was then given Ⅳ. Succinylcholine 1.5 mg?kg-1 was given to facilitate intubation after the patients lost consciousness. BP and HR were recorded immediately before induction of anesthesia (T0, baseline), immediately after intubation (T1 ) and at 2, 5 and 10 min after intubation (T2 ,T3 ,T4 ) . Cardiovascular intubation response was defined as increase in SP or HR by 15% of the baseline value within 2 min after intubation. Blood samples were taken at T0-4 for determination of plasma concentration of norepinephrine (NE) and epinephrine (E) by HPLC. Side effects such as chest wall rigidity and hypotension were also recorded. Results The cardiovascular intubation response rate was significantly higher in group A (80%) than in group B (10% ) and C (10% ) . The incidence of side effects was significantly higher in group C (70% ) than in group B (20%) and A. Plasma NE and E concentrations were significantly increased after intubation in group A (at T2-4) and B (at T2,3) as compared with baseline values at T0; while in group C only plasma NE concentration was significantly increased at T2 and T3 and there was no significant change in plasma E concentration after intubation. The plasma NE and E concentrations were significantly higher in group A (T2-4) and B (T2,3) than in group C. Conclusion The appropriate infusion rate of remifentanil for tracheal intubation is 0.10 ?g?kg-1 ?min-1 in older patients.

It is pointed out that nursing personnel at the clinical forefront are a high-risk group for occupational injuries. The risk factors include: lack of knowledge on occupational injuries and their prevention in elementary and continuing education; various factors affecting nursing personnel's physical health, such as drug-dissolving facilities for the special purpose of chemotherapy, imperfect clean work station or relatively hermetical drug-dissolving environment ; increase of diseases that could be easily contracted in the hospital, such as hepatitis B, with the stabbing of nursing personnel by sharp medical instruments infected by blood or saliva being the main route of their occupational infection. The disadvantageous impact of occupation on their health puts nursing personnel under great psychological pressure. In order to safeguard their physical and mental health, it is imperative to put knowledge on hospital infection, occupational injuries and health maintenance on the curriculum of medical colleges and universities, reinforce nursing personnel's training in occupational safety, and take measures to prevent occupational injuries, such as using disposable gloves when dispensing medicines in chemotherapeutic drug centers.

Objective To observe the effect of Exendin-4 on the apoptosis of cardiomyocyte induced by H2O2,and approach the relationship between GLP-1 signal pathway and the injury of cardiomyocyte.Methods Cardiomyocytes were isolated and cultured,and were divided into 5 groups.Intercelluar ROS (reactive oxygen species) was measured,and cell apoptosis rate was evaluated by Flow cytometry in different groups.Also expressions of apoptosis-associated proteins (caspase-3) and PI3 K/AKT were evaluated by western blot.Results Compared with H2O2 group,Ex-4 co-incubation decreased the production of intercelluar ROS levels,also improved the cardiomyocyte apoptosis.At the same time,Ex-4 resulted in the alterations in expressions of the caspase-3 and p-AKT/AKT proteins.However,these effects of Exendin-4 were counteracted significantly by the co-incubation of LY294002.Conclusion The interventions of GLP-1 signal pathway can improve cardiomyocyte apoptosis induced by H2O2 incubation,and the mechanisms might partly attribute to the PI3K/AKT system.

Objective To observe effect of aerobic exercise combined with inhalation of tiotropium on patients with stable chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension.Methods A total of 98 patients with stable COPD and grade Ⅱ or Ⅲ pulmonary function complicated with pulmonary hypertension were recruited.They were divided into an observation group (n =31) and two control groups (n =30 and 37).Patients in control group 1 inhaled shahmette and fluticasone powder,and antibiotics as well as apophlegmatisant were also used in accordance with the demands of the patient's condition.Patients of in control group 2 inhaled tiotropium dry powder and accepted other therapeutic measures equivalent to those of control group1.The patients in the observation group were given aerobic exercise in addition to other therapeutic measures equivalent to those of control group 2.Six-minute walk test distances,pulmonary arterial systolic pressure and chronic obstructive pulmonary disease assessment test scores were compared after 6 months of treatment,among the groups and against the baseline values before treatment.Results After 6 months of treatment the average 6-minute walk distance,chronic obstructive pulmonary disease assessment score and pulmonary arterial systolic pressure of the observation group were all significantly better than for either of the control groups.Conclusions Inhaling tiotropium dry powder combined with aerobic exercise can reduce pulmonary artery systolic pressure and improve the symptoms as well as the quality of life for patients with stable COPD complicated by pulmonary hypertension.
